S4PST: Advancing the Programming Systems Ecosystem for Future HPC

The successful completion of the US Department of Energy (DOE) Exascale Computing Project (ECP) has highlighted the crucial role of software in maximizing the potential of heterogeneous extreme-scale high-performance computing (HPC) systems. To ensure that future HPC systems benefit the broadest possible user base, we must invest in a robust and adaptable software ecosystem. Programming systems, as the primary interface for most application developers and users, are essential. Therefore, advancing the programming systems ecosystem requires careful attention.

In this presentation, we will introduce the Stewardship for Programming Systems and Tools (S4PST) project, funded by the DOE Advanced Scientific Computing Research’s (ASCR) Next Generation of Scientific Software and Tools (NGSST) Initiative. This project aims to advance the development and stewardship of ten software products essential for future HPC systems, while also incubating new products targeting the integration of HPC and AI in programming systems (E.g. LLMs, AI, high-productivity languages). We will provide a brief overview of these products, their stewardship teams, key features, recent advancements, and engagement activities.
